I'm new with VUSB, and with AVR.
I've made a working LED cube, and now I'm trying to control it from my PC with USB.
I compiled a vusb test project (https://www.obdev.at/products/vusb/hidkeys.html),
changes the usbconfig.h to match my pins (PB2 and PB3), set F_CPU,
and windows gives me an error message, telling the usb peripherical hasn't worked, and can't be recognized.

Here is the circuit :

AS you see, my AVR is powered with 5V supply, and I need this. So I used zener diodes as said on the wiki.
I'm guessing it's a hardware issue, but I can't figure out what.

Any ideas ?

Thank's for your help anyway !
